The Greens were founded on 23 June 1983. In the 1984 elections, the party got two seats in the Chamber of Deputies. In 1985, however the party split into two separate parties called 'GLEI' 'GAP' . They competed separately in the 1989 election, where they won two seats each.In 1994, the two parties presented a common list for the elections. They won five seats in the Chamber, getting nearly 11% of the votes, which made them the fourth strongest force in parliament. In that year's European elections, which coincided with the national elections, the party won one of the six seats allotted to Luxembourg. In 1995, the two parties merged officially. That same year, the Greens' MEP, Jup Weber, left the party again, forming the Green and Liberal Alliance and joining the European Radical Alliance in the European Parliament.
